"Soooooooo you asked for it . . . an EXCLUSIVE behind the scenes at Kaley Cuoco's wedding. We share the look and some other fun moments as we get her ready," Greenberg captioned the video, featuring herself and hair stylist Faye Woods. "It was a blast to be a part of this EPIC new year's eve/surprise wedding. Come with me and enjoy this candid experience."

Cuoco married tennis pro Sweeting, 26, at the Hummingbird Nest Ranch in Southern California on New Year's Eve. The couple became engaged in September after three months of dating.

"We're here for a very special day," the bride-to-be explained in the video while sitting in a chair and sipping a glass of champagne. "It's New Year's Eve and I'm throwing a big, big party . . . I can't wait. But, there's one special thing that might happen tonight: I'm getting married!"

Watch a behind-the-scenes video of Kaley Cuoco getting her makeup and hair done for her Dec. 31 wedding to Ryan Sweeting.

In the video, Greenberg explains each beauty step while perfecting Cuoco's makeup. She gave her a sexy cat-eye liner with pink eyeshadow for her big day. "I have a lot of servants today," the CBS star joked. "They like it. I pay them in gum."

As for her hair, Cuoco decided to honor her husband-to-be's wishes by wearing her blonde hair down in soft curls. "My fiance, I said, 'Is there anything that you want or feel that you want from me? Because he didn't get to pick anything in this wedding. He was like, 'I just want your beautiful hair down,'" Cuoco explained. "So, Faye, if you mess this up, Ryan is going to be pissed."

Fortunately, the bride was very pleased with her final look. "I feel unbelievable. This is my custom gown by Vera Wang; I wanted to wear pink. I can't wait to go get married to Ryan," she said. "I'm not nervous at all. I've never been less nervous in my entire life."
